Light, straight and pre-punched
C sections are roll-formed from galvanized coil and used as purlins, girts, eave struts and light framing. They are cut to length and punched to the connection layout in-line, so members arrive ready to bolt. Simple spans and short projects use C sections; continuous lapped systems usually use Z purlins.

자주 묻는 질문
What is the maximum C purlin depth?
Standard sizes go to C300; the auto-size line rolls any depth from 100 to 400 mm and flange widths from 50 to 130 mm.
Can holes be punched to our layout?
Yes – holes are punched in-line to the connection layout from the shop drawings.
